ROLLS FOR THE MANUFACTURE OF SHOVELS, SPAJDES, 8w.

To all whom it may concern:

Be it known that I, JOHN A'rKINs, a subject of the Kingdom of GreatBritain, residing at 51 Snape Hill, Dronfield, Sheflield, in the countyof York, England, have invented certain new and useful Improvements inRolls for the Manufacture of Shovels, Spades, and Similar Articles, ofwhich the following is a specification.

This invention relates to improvements in rolls for manufacture ofshovels and spades and its object is to enable the breaking down andfinishing processes hitherto employing several men and machines, to becarried out on a single machine whereby the amount of time and laborincurred in the production of the articles are substantially reducedwithout prejudicing in any way the quality or finish of the goods turnedout, while the invention is also characteristic in that the whole of theprocesses before mentioned may be effected at a single heat, it beingthereby unnecessary to return the articles to the furnace either for thepurpose of reheating or for conserving the heat between the variousstages of the processes from which it will be obvious that aconsiderable economy is effected in the fuel consumed and in the numberof attendants required for the furnaces.

According to this invention the various rolls which are necessary toeflect the breaking down and finishing processes are combined in onemachine, and the different prints or recesses are so disposed andarranged on the periphery of the rolls that substantially the entiresurface thereof is utilized and instead of several pairs of rolls beingrequired the number is reduced to one set of three high rolls. Theprints are arranged in such relation to each other that the blanks areadapted to successively traverse the rollers in alternate directions sothat the blank is fed by one attendant from his side of the machine andpassing therethrough it is reversed by the attendant on the other sideand so on until the blank arrives at the finished condition, that is,ready to be sheared to the correct dimensions which may be done by anysuitable machine. Further, for convenience of manipulation the steps orstages may advantageously be such that the one attendant feeds theblanks to the upper roller and the Specification of Letters Patent.

attendant on the opposite side delivers them to the lower spaces bywhicharrangement it will be seen that liability to error on the part ofthe attendant is materially reduced.

In order that this invention may be clearly understood and more easilycarried into practice reference may be had to the appended explanatorysheet of drawings upon which the figure is a diagrammatic frontelevation of a set of rolls constructed and arranged according to thepresent invention, the depth of the prints or passes being exaggeratedfor the purpose of more clearly illustrating the improvements.

In an embodiment of this invention such as illustrated by the drawingsthe machine comprises three rolls A, B, C, disposed one above the otherand journaled in suitable housings D, the middle and lower rolls B, Gbeing driven by pinions (not shown) and the upper roll A by frictionfrom the central roll B. The upper roll A has two main prints orrecesses a 66- therein each about one third of the length of the roller,the middle roll B has one narrow print 5 near its one extremity and thelower roll C has one print 0 extending over rather more than half of itslength. To render the sequence of the passage of the blank through therolls quite clear I havedesignated the point at which the stages ofreduction takes place by numerals arranged in order corresponding withthe sequence aforesaid and it will be noted that the blank emerges fromthe rolls after its final pressing, on the opposite side to that whereinit was first inserted as a bar, which system is advantageous by reasonof the raw material being located on the one side and the finishedarticle on the other.

Following the progressive action of the material through the machine,the bar is first heated to a temperature appropriate for the purpose inview and inserted at 1 where it undergoes the first step of the breakingdown process, the collars a b and shoulder b preventing the bar fromspreading out to an excessive degree, the blank subsequently passingthrough the various stages in alternate directions as denoted by thenumerals 2, 3, 4, 5, 6 until it passes through the last print 7 which isprovided with a recess E for forming the extra thickness of the langetand its con- 'nectingpart leaving the rolls ready, for

and as such screws together with the housskilled in the art, furtherdescriptionlof 'The rolls are adaptable to langet spades and shovels,open socket, stamp steel and other types of shovels and the invention isnot restricted to the. particular disposition I of the prints or passesprovided that the I progressive or cumulative effect of the stages isobtained from a single set of rolls. 1

Having now described my invention, I declare that what I claim is I11the hereinbefore described device for the manufacture of.shovels andspades, the

combination of an upper roll having three 20 prints of approximatelyequal length, a lower roll having a print extending about two-thirds ofits length, and an intermediate roll having a short print near oneextremity.

In witness whereof I have hereunto set 2 my hand in the presence of twowitnesses. JOHN ATKINS. Witnesses:
